- 論文の詳細を見る
We derive the Landau-Migdal parameters g'_N for nucleon particle-hole states, g'_Δ for nucleon and delta particle-hole states and g'_<ΔΔ> for delta particle-hole states within the π+ρ model. The density as well as the momentum dependences of these parameters are studied. The three parameters turn out to be about 0.6-0.65 in the pion mass unit at zero momentum, once the contribution from other channels, especially the non-spin non-isospin channel, and those from the induced interactions are included.
